RAILWAY SIGNALING SYSTEM.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed July 29, 1910. Serial No. 574,485.

To all whom it may concern:

Be it known that I, ALPHONSE RIOUX, a citizen of the United States, residing at Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Rail.- way Signaling Systems; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is the arrangement of means for indicating the condition of the track by sounding an alarm in the 10- comotive as the same approaches a broken rail or a broken or removed tie.

With these and other objects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a longitudinal vertical section through a bridge with the invention applied thereto, disclosing how the circuit is closed when a tie is broken. Fig. 2 is a detail sectional view through a contact member embodying certain features of the invention.

In constructing a signaling system, embodying the invention, for signaling trains the condition of the track in front of the same, a system of wiring is provided adapt ed to be switched into and out of operation by the position of the various ties to which the system may be connected for causing or not permitting current to flow through the alarm mechanism of the various trains.

In order that the invention may be more clearly understood an embodiment of the same is shown in the accompanying drawings, in which 1 indicates a track.

In Fig. 1 will be seen an embodiment of the invention, in which means are provided for signaling a train when a tie has been broken or removed as from a bridge. This form of the invention is preferably applied to bridges as a safeguard, and in applying the same a rod 20 is connected with each of the ties 21 and is supported thereby. Rod 20 passes upward through contact members 22 and 23. Contact member 23 is insulated from its support 24 which is a metallic member acting as an electrical conductor, while contact 22 is rigidly secured thereto, and connected therewith electrically. An insulating spool or block 25 is provided for, preventing current from passing from contact member 23 to contact member 22, through rod 20. The support 2 L holds in position all of the contact members 22 and 23 on the bridge, and is electrically connected by wire 26 to trolley wire 9. Each of the contact members 23 is connected with station wire 27 by wire 28. Interposed between wires 9 and 27 at any desired place, and electrically connected therewith, is a bell or other signal, so that whenever the bridge is destroyed, or any one or more ties 21 broken or removed, a signal will be sounded at the station or at the point where the bell is located. When one of the ties 21 is removed rod 20 will drop, and by its weight close contact members 22 and 23, so that the circuit is closed at that point, through a bell, and a suitable source of current (not shown).

lVhat I claim is:

In a signal system for railways, a signal, a circuit including a circuit closer comprising contact arms formed with an aperture in each arm, means for rigidly supporting said arms, means for insulating said arms, an insulating sleeve fitted into the aperture in one of said arms, and a headed rod normally supported by one of the ties of said railway extending through the apertures in said arms and held out of contact therewith by said insulating sleeve, said rod being adapted to cause said arms to contact upon the removal of the tie supporting the rod.

In testimony whereof I atfiX my signature in presence of two witnesses.
